Product Description
This product is a disposable square kraft paper bowl made of high‑grammage kraft paper, offering excellent rigidity and oil/water resistance. The square design saves storage space and prevents rolling during transport. It is suitable for cold and warm foods, with three inner coating options: uncoated, PE coated, or PLA fully biodegradable coated. The uncoated version is for dry foods (e.g., bread, nuts); the coated versions effectively block oil and moisture, making them suitable for dishes with sauces or broth. The overall structure is reinforced – the bottom has no folded crease and provides strong load capacity, resisting deformation after filling.

Key Features

• Material: Food‑grade kraft paper (virgin bamboo pulp or pure wood pulp), no fluorescent whitening agents, safe for direct food contact.

• Grammage: 350g, 400g, 450g – thick and sturdy, will not collapse when filled with moist foods.

• Shape: Square – clear edges and corners, stacks stably, saves about 30% warehouse space compared to round bowls; fits neatly into delivery bags without rolling or tipping.

• Coating Options:

  • Uncoated – for dry, cold foods, maintains natural paper breathability.

  • PE coated – ordinary water and oil resistance, cost‑effective.

  • PLA coated – fully biodegradable and compostable, meets single‑use plastic ban requirements.

• Leak Resistance: Reinforced bottom fold with no gaps; coated versions tested with oil‑based dressings or liquids – no leakage or wicking for 2 hours.

• Temperature Range: Uncoated version – room temperature and refrigeration (0~40°C). PLA coated version – -10°C to 80°C, suitable for warm meals but not for boiling liquids.

• Assembly: Pre‑creased, folds into shape in 3 seconds without glue or tools; edges have anti‑lift design that self‑locks after folding.

• Lid System: The rim is compatible with two lid types:

  • Transparent PET lid (high clarity, anti‑fog, tight seal)

  • Kraft paper lid (same material, printable, biodegradable)
    The lid and bowl together create a seal that reduces spillage during transport.

• Custom Printing: Supports 1–2 colour flexographic printing with water‑based inks, can print brand logos, product info, eco‑labels, etc. Printing area is on the outer wall or lid surface.

• Stackability: No protruding parts, multiple units can be stacked flat for easy storage and dispensing.
